Question

2. In the figure given below, the bisectors of ABC and BCA, intersect each other at point
O. If BOC = 100°, the A is

(a) 300
(b) 200
(c) 400
(d) 50°​

Answer 1

x + y + 100° = 180°

=> x + y = 80°

And, 2x + 2y + z = 180°

=> 2(x + y) + z = 180°

=> 2(80°) + z = 180°

=> z = 20°

Hope, it'll help you.....
